Ground granulated blast furnace slags (GGBS) are glassy by-products from iron production that commonly used as supplementary cementitious materials in blended cements. The glass structure of seven industrial GGBS was investigated by Raman and nuclear magnetic resonance spectroscopies. complex composition the induced multiple analytical challenges. Under usual continuous excitation, signal maske...

The first silver-FOX, silver-ammonia-FOX, and silver-amine-FOX compounds were synthesized by the reactions of silver nitrate with K-FOX or guanidine-FOX in water, aqueous ammonia, and amines, respectively. The crystal structure of silver-ammonia-FOX exhibits unique covalent bonding behavior, which is supported by NBO calculations.

Two isomeric phases of the NbO-type structure have been discovered: PCN-16 (alpha phase) and PCN-16' (beta phase), and gas sorption studies revealed that the alpha phase possesses a larger surface area, leading to higher hydrogen and methane storage capacity as compared with the beta phase.

A copper-based NbO-type metal-organic framework constructed from a tetracarboxylate incorporating phenylethyne as a spacer exhibited an exceptionally high methane working capacity of 184 cm(3) (STP) cm(-3) for methane storage. The value is among the highest reported for MOF materials.

High-entropy effect is a novel design strategy to optimize properties and explore materials. In this work, (La1/5Nd1/5Sm1/5Ho1/5Y1/5)NbO4 (5RNO) high-entropy microwave dielectric ceramics were successfully prepared in the sintering temperature (S.T.) range of 1210–1290 ℃ via solid-phase reaction route, medium-entropy (La1/3<...

Lead-free piezoelectric one-dimensional (1D) nanostructures have exhibited great potential in building biocompatible micro/nano-energy harvesters and self-powered smart sensors. However, their low coefficient still remains as the biggest obstacle for practical applications. In this work, an ultrahigh with calibrated d 33 from 400 pm V -1 to 814 is achieved Li-doped (K,Na)NbO 3 (KNLN) lead-free ...

A new NbO-type metal-organic framework ZJNU-40 incorporating highly polarized benzothiadiazole moieties exhibits a high CO2 uptake of 108 cm(3) g(-1) at 296 K and 1 atm, as well as good adsorption selectivities of CO2 over CH4 and N2 at room temperature, which is superior to that of the analogous MOF NOTT-101.

A new bulky pyrene-derived elongated cross-shaped organic scaffold was successfully incorporated into a highly porous, noninterpenetrated square-grid copper(II)-organic framework material with the unprecedentedly huge dimensions of 25.5 x 25.5 A(2), while the layer-to-layer NH...N interaction leads to a unique hydrogen-bonded 6(4).8(2)-nbo net.

Hyperbaric oxygen (HBO) therapy has a number of clinical applications. However, the effects of acute HBO on basal cerebral blood flow (CBF) and neurovascular coupling are not well understood. This study explored the use of arterial spin labeling MRI to evaluate changes in baseline and forepaw stimulus-evoked CBF responses in rats (n = 8) during normobaric air (NB), normobaric oxygen (NBO) (100%...
